MUSIC-PLAYER WINDING AND ELECTRIC SHIF'IER.

Application tiled July 16, 19??.

To all whom z' may Concern.'

Be it known that I, RoBnR'r A. GALLY, a citizen of the United States, and residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented vcertain new and useful Improvements in h/iiusic-Player lliindings and Electric Shifters, of which the following is a specification.

In the prior art of automatic shifting and control of the winding and rewinding and repeating of an automatic music sheet the patent of M. Gally, #22,030, November 1879, shows the earliest example, being shown at the right of his Figure l, and described on page 3 of his specification, while a later important development isv that of Arno, #596,768, January il, 1898, which inlclndes means for stopping the electric driving power of his instrument. ln the present application are shown various improvements whereby the music sheet may be automatic: lly controlled from its own operation to reverse itself from forward playing operation to its rewind operation, and from re wind motion to repeat its forward playing, also means to interrupt such repeating when desired and cause it to stop'thc electric Amotor at said interruption of its travel; and to stop its motion and the operation of the electric motor whenever a music roll without a repeat control perforation reaches the end of its rewinding` travel and uncovers the tracker bar.

ln the accompanying drawings, Fig. l. is a front view of a n isic' player tracker, rolls and winding mechanisi with the shifter for the roll travel and electric switch set` for starting the forward motion of the sheet for playing music; the repeat perforation beinel in active coincidence with the repeat aperture of the tracker bar; Fig. :3 is of the saine parts with the music sheet at the linish of its forward playing and its rewind perforation coincident with the rewind cont rollingl aperture of the tracker bar; Fig. Il is of the same parts with the music sheet fully rewound and off the tracker, thus openingsboth the rewind and repeat apertures of the tracker and bringing` the shifter means to a `median position with the electric motor cnt ontof operation. Fig. 4v is a side view of the inside of the right hand side, showing Specification of Letters :Pa/cent.

musical apparatus, not necessary to be f shown and described herein, and the electric switch here shown is understood to be of any suitable detailjand to be connected to an electric circuit in which are a current source, and a motor` the motor being` utilized for operating an air pnniper, or supplying power in any suitable manner for operatine' the playine'. winding and rewinding' and shifting' devices. ln the shifting` devices as shown. it is understood that air power is supplied by any suitable air current inducing means, and that a variation of such air service is effected by pneumatic means not shown, but understood to be of any suitable type. and to be controlled by some pneumatic means equivalent to that shown in the drawing herein. Except for the par ticular features claimed with the electric switch as an element, it is to be understood that the operating.,r power inav be produced .j Abv any other power than electric motor. as

by foot. and that the tracker and connections 'therefrom may be electric or mechanical. etc.. instead of pneumatic, and various other equivalents or substitutions employed withont. departing from the spirit of the invention herein set forth.

A music sheet l has the usual roll. Q there with adapted to be encaeed by a nd'- revel ved with a clutch spindle 3. it take-np spool .f has the usual means for temporary attach ment of the forward end of the music sheet l. and this spool et has its shaft 5 extended 'therefrom and a clutch (3 atlixed thereto. je. gear wheel T is loosely mounted on the spool shaft, 5 and this gear wheel 7 has attached thereto a grooved collar S. the groove of which is engaged bv a pinor lug on the shift lever S). which shift lever 0 is suitably pivoted at its upper end on the fixed bearing,r hub l] or other fixed part ofthe apparatus.

A pinion 'l2 and :i suitable ,Q'rooved collar l are both tixed to a revolnble drive shaft it. the groove of the collar 'i3 being,r engaged blv a pin or lug' of the shift lever fgthe right end of shaft '14 extending into a const revoluble engagement with the motor shaft 15 of any suitable motor, such as the usual wind or clock motor of player devices. The engagement of drive shaft 14 and motor .shaft 15 is by means of their respective clutches 16 and 17, which, while insuring the revolution of drive shaft 14 whenever the motor shaft 15 is revolved, allows the lengthwise movement of drive shaft 14 by action of the shift lever' 9, thereby enabling the engagement of the clutch pin 18 on the gea-r wheel 7 with the clutch 6 of the spool shaft 5 when-the shift lever 9 is moved to the eXtreme left by the handle 19, or as in Fig. 1 by the rod 2O when said rod is automatically shifted to the left by motor pneumatic 21 when said pneumatic is exhausted from valve 22 When said valve is actuated from the repeat aperture 23 of the tracker 24 when said aperture 23 is opened by the repeat perforation 25 of the music sheet 1, the engagement of'said two clutches 18 and 6 then enabling the revolution of the shaft 5 and its spool 4 from the drive shaft 14 through pinion 12 meshed with the gear 7.

Then the handle 19 is shoved to the right by the person using the apparatus, or, as in Fig. 2, the rod 20 is moved to the right by ,motor pneumatic 26 when said pneumatic is exhausted from valve 27 when saidv valve is actuated from the reroll aperture 28 of the tracker 24 when said aperture 28 is opened by the reroll perforation 29 of the music sheet 1, the shift lever`9 is moved to the right and the shaft 14 and clutch 30 fixed with said shaft 14 then engaging the lclutch 31 ofthe sprocket wheel 32, thereby causing said sprocket wheel 31A to revolve I,and through chain 33 revolve the small sprocket wheel 34 which is fixed on clutch spindle 10, 'thus causing the said clutch spindle 10 and clutch 3 to revolve and turn the roll 2 and rewind the music sheet 1 on said roll 2 ready for repeating or for removal from the apparatus.

W'hen the reroll position is in effect, as just described, and as shown in Fig. 2,

` clutches 18 and 6 are free of engagement and the gear wheel 7 can then revolve freely on spool shaft 5 as the pinion 12 revolves it, but allowing theshaft 5 and its spool 4 to revolve inthe opposite direction as the music sheet 1 is drawn from spool 4 by the rewinding of said sheet 1 on its roll 2, as said roll 2 is turned by clutch 3 and spindle 10. l

It is desirable to place the repeat aperture 23 nearer to the position of one edge of the music sheet 1 than the position of the reroll aperture 28 to the other edge of the music sheet 1, or both the said apertures in similar relatioh to one edge, so that when a music roll and sheet are placed in the'apparatus and the V-shaped forward end of the sheet is drawn down over the tracker fore or as soon as the closing of the repeatv aperture 23, to avoid an .improper leading action of the reroll aperture which would i prevent the insertion of a roll were the distances of 4these two apertures reversed as to their relative distances from the edges of the music sheet. The two apertures might be placed at equal distances from the two edges of the music sheet, but this Would cause the risk 'of trouble if the sheet were diverged to the slightest degree from its middle position as it was drawn over the tracker.

When it is desired to prevent the repetition of a music sheet which has arepeat perforation as 25the interrupter or catch 3'5 is set -in its forward position as shown in Fig. 4, and thus the notch 36 of thehandle 19is caught by said interrupter or catch 35 by the leftward motion'of shifter 9 and clutch 30 is clear from Iclutch 3 1, and clutch 18 is clear from clutch`6, whereby the revolution of drive shaft 14 causesv no revolution of either spool shaft 5 and spool4, or spindle 10, clutch 3 and roll 4, and the 'music roll 4 and sheet 1 come t0 a standstill and may be removed from the apparatus. The

cleail of the handle 19, whereby the handle y 19 is free to move all the way to the left to accomplish the shift of parts necessary to securethe repetition of the forward travel of the sheet 1 for another playingof the music thereof.

When a music sheet as 1 has no repeatperforation as 25, and the interrupter 35 is thrown off its engaging position for notch 36 of handle 19, or if there be n o interrupter means provided, the return travel of the music sheet 1 will continue until it has uncovered repeat aperture'23 of the tracker 24, thus causing the shifting means to start to the left, but the reroll aparture 28'will also be uncovered by the sheet 1, and the action of the motor pneumatic 26 toward the right will thereby check the leftward repeat shift motion, the motors 26 and 21 coming to rest at a middle balanced position, stopping the rod 20, and shift middle position when the clutches 18 and 6, and 30 and 31 are disengaged, and the revolution of both roll 2 and spool 4 stopped and the music sheet brought to rest. If it is then desired to repeat the playing' of the same music sheet, it is only necessary to press down the handle 19 to release its notch lever 9 at'the music sheet 1 at rest and the wind motorBS cut off from. air supply, as in Fig. 3, the electric switch is put in open circuit and the said electric motor and the air inducing means are stopped.

Although this result could be had with a special switch, that is, a switch made to close the circuit at each end ofl its motion, and open the circuit at the middle of its motion, making two jumps each way, no such switch is on the market, so a novel means is here shown for this special three position action with an ordinary snap switch as 44, the broader claims of the application as `to these electric cut-out means being worded to cover any manner of a three position action of an electric cut-out for the purposes herein set fort-h.

- lith the ordinary push and pull switch 44 shown herein, the three position control is attained by a cam slide 45 connected at its right end to the shifter rod 20 which has a V-shaped cam way or slot 4G working on a fixed bearii'ig 47, and this slide 45 also has a straight'slot 48 workingon a'iixed bearing 49, these two bearings 47 and 49 being in an approximate line with the main dimension of shifter rod 20, and the shifting motion of both rod 20 and cam slide 4G being in substantially that same general line as the shifter rod 20 and slide 46. A connecting rod or similar member 50 is attached to the left end of the cam slide 45 and to the moving member 51 of the switch 44.

l/Vhenever the shifting means are moved to the left for the forward winding and playing as in Fig. 1, the rod 2O pushes the cam slide 45 to the left so that the right hand and low part of its cam way 4t engaging' the bearing 47, thus throwing` the left end ofthe cam slide 45 upward.V and thus by means of rod 50 pushing up the movingmember 51,0f switch 44 and closing the electric circuit for the operation of the electric motor which furnishes the power i for playing the apparatus.

When the shifting means are thrown to the right for rewinding of the music sheet 1 as in Fig. 2, the rod 2O pulls the cam slide 45 to the right so that the left hand and low part of its cam Way 46 is engaging the bearing 47, thus throwing the left end of thc cam slide 45 upward and thus by means of rod 50- pushing up the moving ymember 51 of switch 44 and closing the electric circuitfor the operation of the electric motor which furnishes the power, whichpower is then used for the rewinding of the music sheet 1.

When the shifting means are brought to the middle position to cause the music sheet 1,. roll 2, clutch 3, etc., to be at rest, and enable the ready removal and change of music shecls, as in Fig. 3, the rod. Q0 holds the cam slide 45 at its middle position of movement` with the middle and high part of its cam way 46 engaging the bearing 47 thus throwing the left end of the cam slide 45 downward and thus by means of rod 50 pulling down the moving-member 51 of the switch 44 and opening the electric circuit against operation of the electric motor, thus bringing every element of the apparatus te a condition of rest and quietness, and preventing any waste of current, yet enabling the restarting of playing operation by use of but the one handle 19, the movement of same to the left instantly restoring the electric current for playing.

The bearing 49 acts as a second guide for cam slide 45, and is a pivot on whichl said cam slide 45 swings when its left end rises and falls.

The shifting movement from left to right, or right to left, passes the middle position of broken circuit so quickly, that there is practically no stoppage of the electric motor, its momentum carrying it over the small moment of current breakage.

The various novel details of the constant mesh gears and simplified drive, and clutch changing of the winding and rewinding parts herein set forth, being useful independently of their present shown use with the special automatic shifters, electric cutouts, and other features claimed herein, such gearing, drive and clutch means, and also the general use of the three position control of a single motion electric switch and the particular cam form shown therein are claimed .in an appropriate sepa ate application #190,674, led Sept. 10, 1917, also, various modifications may be made in the structure of the means for seeming a three position control of a single switch, or a special switch may be employed having two closed positions and an intermediate open position of its action, and yet be subject to the claims hereof; but, what I claim as my invention, is:-
